= Pacpus components must inherit QObject =

Components that use the input / output mechanism of Pacpus must inherit QObject: 
- Take care that QObject requires to be first in multiple inheritance (see extracted documentation below). 
- Don't forget the macro Q_OBJECT in the class declaration

{{{
Multiple Inheritance Requires QObject to Be First

If you are using multiple inheritance, moc assumes that the first inherited class is a subclass of QObject. Also, be sure that only the first inherited class is a QObject.
// correct
class SomeClass : public QObject, public OtherClass
{
    ...
};
Virtual inheritance with QObject is not supported.
